n 2 Claims. 'Ihis invention relates to a container having structurally and functionally improved characteristics.

It is an object of Ithe invention Ato furnish a container which wiil'provide an end seal structure such that it maybe subjected to considerable abuse without its becoming damaged. A further object of the invention is that of `providing a container in which a seal will be embodied such that under all conditions of service an escape of the contents thereof is virtually precluded. Y

A still4 further object is that of furnishing a container which will tend to automatically assume a proper position or relationship with respect to adjacent containers and during shipment such that any danger of an individual container being injured will be reduced to a minimum.

Another object is that of furnishing a con` tainer embodying the foregoing advantages and which container may be manufactured largely by automatic machinery and simple methods so that the unitmay be placed upon thenmarket at a nominal ligure.

With these and other objects in mind, reference ishad to the attached sheet of drawing,

` in'which:

Fig. 1 is a side elevation of a container with certain portions -of the same broken away and showing underlying portions in section; i

Fig. 2 isa fragmentary enlarged sectional view showing the container with an end seal applied thereto;

Fig. 3 is a view similar to Fig. 2, but showing the end seal or closure subjected to a second stage of development;

Fig. 4 is an additional viewfof this nature, but showing the closure in its final or applied condition;

Fig. 5 vis a partly sectional and fragmentary side elevation showing a number of the closures in the relative positions which they may assume and Fig.v 6 is a diagrammatic view illustrating in exaggerated form an ideal relationship of the Darts.

Referring primarily to Fig. l, there has been shown a container, the body of which may be in the form of a cylinder I0, formed of any suitable material, and the ends of which are sealed by heads or caps generally indicated at I I. Each of these caps preferably embraces a disk I 2, which maylie within the bore of the cylinder or container body and transverse to the longitudinal axis thereof. The caps may be formed of suit- (Cl. 22B-5.5)

. is to intimately engage the end or lip of the container body. Beyond this point the cap is continued in the form of a portion generally indicated at I5 and which portion is to intimately engage the outer face of the container body.

In applying the cap or end seal to theV container, it will be `understood that this seal is initially supplied in the form of a member as shown in Figs. 2 or 3. In other words, the disk portion I2, flange I 3, and enclosing portion I4 are already in existence, but the portion I5 .simply extends outwardly and terminates in a straightedge portion .which maybe subsequently bent as at I6 in Fig. 3, or which may be formed prior to the association of the container with the end seal. Regardless, however, of whether the bead is preformed or not, it is obvious, by simply forcing the edge portion of the container into what might be termed the gasket portion of the end seal, the parts will assume the positions shown in Figs. 2 and 3. Afterwards the portion I5 may be bent so that it extends into intimate contact with the outer face of the container as has been shown in Fig. 4.

Of course, when the end seal is initially applied to the container, this is usually done with sufficient force to cause the edge portion ofthe container to mushroom to some extent. This 35 expansion of the container body adjacent its edges may be to only a microscopic amount, but in any event will be sufiicient to insure a great intimacy of contact between the container surfaces and the adjacent and contacting surfaces of the 40 seal. Asthe portion I5 is bent into intimate contact with the outer face of the container, it is obvious that the body of the container (especially vwhen formed of brous or similar materials) 1 as indicated especially in Fig. 4. it will be obvious that a seal is furnished which will have at least ive zones or points of sealing, any one of which would be normally adequate to prevent the escape of iuid or other material from the container. One of these zones dened by the face of the flange I3 exists, of course, between the inner face of the container and the ange. The second zone exists within the area of the bent portion Il, especially when one considers that in manufacture the edge of the container is rammed home withinv the grooved structure furnished by lthe with. It is obvious that as a consequence of this v structure an escape of material from within the container is almost precluded regardless of the abuse to which the container is subjected.` This is lespecially true by virtue of the fact thatthe bead I6 liesin a plane short of that of the disk I2, and -thus a counter-bracing structure is furnished'which draws the outer face of the iiange I3 into intimate contact with the adjacent ycontainer surfaces; Y

Moreover, by this construction an especially rigid structure is furnishedrsuch that the containers may even be droppedwithout there being any danger of collapse of 'the end seals of the adjacent rcontainer portions.'

It will.additionally be noted that the groove or recesses furnished by the ilattened orinwardly extendingportion I'I is of suillcient area to accommodate either that portion of the flange I which is below the same), or the bead portion Il of an adjacent container.

It has been found that in placing a number of containers within a carton that in shipment relative shifting occurs between these containers, and

` thatjeither the bead or the lower edge portion of a sealy tends to ride into the groove or recess deilned by the inwardly extending portion I1 of an adjacent container. In other words, the con- 5o tainers tend to'interlock, so that, in eect, a unitary structure is provided, embracing a large number of containers in' which movements oi' individual containers with respect to the others virtually becomes an impossibility. This, of course, serves to protect the entire shipment and prevents one container damaging an adjacent container, as all of them are subjected to lvibration incident to cartage or otherwise.

With a View to avoiding unnecessary illustration, the end walls have, in the present instance,

been shown asincluding disks I2, which must be cut away. or otherwise rendered inoperative to gain access to the containers. While this is in -certain respects a preferred construction, it is obvious that in lieu of these disks which require destruction, removal, or mutilation, any other form of readily accessible structure might be utilized. Also, numerous other changes in construction might be resorted to without departing from the spirit of the invention as dened by the claims. f Y

Having described the invention, what is claimed is: f

1. An end seal for a container presenting in section an end wall and a generally U-shaped channel portion projecting from the edges oi said wall and perpendicular with respect tothe same, said portion in section including an inner plane arm to lie in flat face-to-face contact with the wall of a containerwith the edge of said wall lying within the crotchiof such portion, the ,outer arm of said portion being of a height less than the inner arm and presenting a plurality of inwardly and outwardly curved surfaces to lie in intimate contact with the outer face of said container body. Y

2. An end seal ,for a container presenting in section an end wall and a generally U-shaped channel portion projecting from the edges of said wall and perpendicular with respect to the same, said portion in section including an inner plane arm to lie in flat vface-to-,face contact with the wall of a container with the edge of said wall lying within the crotch of such portion, the outer arm of said portion being ofY a height less than the inner arm and presenting an inwardly crimped edge portion and an inwardly indented portion intermediate such crotch and such edge portion, the outer surface of the container body being intimately engaged bythe inner surface of said arm throughout the entire area ofthe latter.
